Abstract
Bu çalışmada, iki farklı besi danası ırkı rasyonlarında farklı enerji kaynakları kullanımının kuru madde tüketimi, yemden yararlanma oranı, taban yastığı kalınlığı ve ayak sağlığı üzerindeki etkilerinin araştırılması amaçlanmıştır. Çalışma Ocak-Temmuz 2020 tarihleri arasında Bomonti Hayvancılık işletmesinde (Kırklareli, Türkiye) gerçekleştirilmiştir. On dört Holstein friesian besi danası (405 50 kg başlangıç vücut ağırlığı) ve on dört Simmental besi danası (450 50 kg başlangıç vücut ağırlığı) rastgele dört gruba ayrıldı ve her grup 7 hayvandan oluşturuldu. Tüm hayvanlar enerji kaynakları bazında yağ kaynaklı veya nişasta kaynaklı toplam karma rasyon (TMR) ile beslendi. Gruplardaki rasyonlar izokalorik ve izonitrojenik olarak tasarlandı. Araştırma sonunda hayvanlar kesime gönderildi. Hayvanlar kesildikten sonra, her hayvanın 4 ayağı toplandı. Toplanan ayaklardaki taban yastıkları ultrasonografi ile görüntülendi. Çalışmanın başından itibaren hayvanların önünde kalan yemler toplandı, gruplar bazında günlük kuru madde tüketimleri ve yemden yararlanma oranları hesaplandı. İstatistiksel analizler SPSS (v28,0) paket programı ve Medcalc (11,5, 2011) programı kullanılarak yapıldı. Yağın ve nişastanın performans üzerindeki etkilerini değerlendirmek için ONE WAY ANOVA kullanıldı. Roc Curve Analizi, hücre infiltrasyonu ve toplanan ayaklardaki taban yastığı kalınlığı arasındaki ilişkiyi değerlendirmek için kullanıldı. Simmental Nişasta (SN) (0.14±0,003) ve Holstein Nişasta (HN) (0.13±0,006) gruplarının yemden yararlanma oranları Simmental Yağ (SY) (0.10±0,008) ve Holstein Yağ (HY) (0.11±0,01) gruplarından daha yüksek bulundu. HY ile beslenen hayvanların taban yastığı kalınlığı (1.2104); HN (1.0993) ve SN (1.1293) (P <0,05) ile beslenen gruplara göre daha yüksek saptandı. SY grubundaki Taban yastığı yağ kalınlığı (1.2289); HN (1.0993) ve SN (1.1293) (P<0,05) gruplarına göre daha yüksek tespit edilmiştir. Hücre infiltrasyonu ile taban yastığı yağ kalınlığı arasındaki ilişki açısından tüm gruplar arasında fark saptanmamıştır. Bu araştırmanın sonuçları dikkate alındığında; yağ bazlı TMR ile beslemenin besi danalarında ayak sağlığı üzerine olumlu bir etkisinin olabileceği sonucuna varılmıştır.
This study aimed to investigate the effects of using different energy sources in the rations of two different beef cattle breeds on dry matter consumption, feed conversion ratio, fat pad thickness and foot health. The study was conducted between January and July 2020 at Bomonti Farm (Kırklareli, Turkey). Fourteen Holstein friesian beef cattle (405 50 kg initial body weight) and fourteen Simmental beef cattle (450 50 kg initial body weight) were randomly divided into four groups and each group consisted of 7 animals. All animals were fed with fat or starch-based total mixed ration (TMR) based on energy sources. The rations in the groups were designed as isocaloric and isonitrogenous. At the end of the study, the animals were sent for slaughtering. After the animals were slaughtered, 4 feet of each animal were collected. The fat pads on the collected from feet were visualized by ultrasonography. Leftover ration in front of the animals from the beginning of the study were collected, and daily dry matter consumption and feed conversion ratios were calculated based on groups. Statistical analyses were performed using SPSS (v28.0) package program and Medcalc (11.5, 2011) program. ONE WAY ANOVA was used to evaluate the effects of fat and starch on performance. Roc Curve Analysis was used to evaluate the relationship between mononuclear cell infiltration and fat pad thickness in collected feet. Feed conversion ratios of Simmental Starch (SN) (0.14±0,003) and Holstein Starch (HN) (0.13±0,006) groups were found to be higher than Simmental Fat (SY) (0.10±0,008) and Holstein Fat (HY) (0.11±0,01) groups. Fat pad thickness of animals, HY (1.2104) was higher than those fed HN (1.0993) and SN (1.1293) (P<0.05). Fat pad thickness in the SY group (1.2289); It was found to be higher than the HN (1.0993) and SN (1.1293) groups (P<0.05). There was no difference between the groups in terms of the relationship between cell infiltration and pad fat thickness. According to the results of this study, it was concluded that feeding with fat based TMR may have a positive effect on foot health.
